You could also get some
Kelly Take Off's to put with whatever brake lever you like, throw some 7900 downtube shifters on there, and you'll be able to shift whatever you want with the friction front and pre-Dynasys RDs. The thing I liked about the Take Offs when I used them on my commuter is that I could keep my hands up on the tops where I had interrupter brake levers or on the hoods and shift easily from either position. Shifting from the drops was hard, but, if this is a touring bike and you think you might be spending a fair bit of time more upright, it's an option to consider.
